If wavelength of photon and electron is ...

If wavelength of photon and electron is same then ratio of total energy of electron to total energy of photon would be

A

`("Velocity of electron")/("Light' s speed")`

B

`("Light' s speed")/("Electron' s speed")`

C

`("Light' s speed")/("Velocity of electron")`

D

`("Electron' s speed")/("Light' s speed")`

Text Solution

Verified by Experts

The correct Answer is:
A
`E=hv=h(v)/(lamda)impliesE prop v` (velocity)
`E_e/E_p = v_e/v_pimpliesE_e/E_p=v_e/c`
